Build machine learning (ML) solutions for Java development. This book shows you that when designing ML apps, data is the key driver and must be considered throughout all phases of the project life cycle. Practical Java Machine Learning helps you understand the importance of data and how to organize it for use within your ML project. You will be introduced to tools which can help you identify and manage your data including JSON, visualization, NoSQL databases, and cloud platforms including Google Cloud Platform and Amazon Web Services.Practical Java Machine Learning includes multiple projects, with particular focus on the Android mobile platform and features such as sensors, camera, and connectivity, each of which produce data that can power unique machine learning solutions. You will learn to build a variety of applications that demonstrate the capabilities of the Google Cloud Platform machine learning API, including data visualization for Java, document classification using the Weka ML environment, audio file classification for Android using ML with spectrogram voice data, and machine learning using device sensor data.After reading this book, you will come away with case study examples and projects that you can take away as templates for re-use and exploration for your own machine learning programming projects with Java.You will:Identify, organize, and architect the data required for ML projectsDeploy ML solutions in conjunction with cloud providers such as Google and AmazonDetermine which algorithm is the most appropriate for a specific ML problemImplement Java ML solutions on Android mobile devicesCreate Java ML solutions to work with sensor dataBuild Java streaming based solutions
